Total Commander

Additionaly to the already suggested Ini entry for Everything search there should be an entry to launch Everything when TC starts, so it has time to update the index.

This would mainly benefit portable installations.

So e.g.:
EverythingTCSearch = "c:\pathto\Everthing.exe -someParameter"
EverythingStartWithTC = "c:\pathto\Everthing.exe -someOtherParameter"

or just
EverythingStartWithTC = true

This can already be done with the TC Autorun content plugin.

Yes, you could use several external/additional methods to achieve this.

But as Everything becomes an integral part of TC, it should natively cover as many use cases as possible (imho).

I could be wrong, but I agree. Just my two cents opinion.

I think Windows provides better ways to handle this task. A scheduled tasks have various execution conditions. So you can start it twice a week at night or only when the PC is idle and so on.

There is of course nothing to say against TC creating such a task - but it would be a bonus.
